Solar Projector: This isn’t anything I invented but in all modesty it is the lightest, safest, best image in any solar projector in a 4 inch size bar none. It is simply a plano-convex lens with a very long focal length (80+ feet) which gives it a large image scale and freedom from color aberration. It’s absolutely safe because the image is never concentrated to cause burns. It is fed by an optical flat and mounts on a camera tripod weighing only 2.2 lbs.. It’s 8 inch diameter solar image is by far the best for group viewing of the sun. Price is $200 plus $15 shipping. Order one this year as I expect to be sold out by the 2017 solar eclipse. There is no better solar projector for public viewing an eclipse.
